Exogyra nana 17 0 The last of these beds makes clear our stratigraphical horizon;and in the absence of fossils, the lithology of bed No. 5 may proveits identity with the false-bedded series of Sturminster. The higherbeds will be referred to again. A similar section to the above is seen in enormous worked-outquarries a little to the west, where the false-bedded series and thesuperincumbent Haggy oolites and marls form a delightful pictureto the geological eye, which we have attempted to pourtray (fig. 3). Fig. 3.— View of Section of False-bedded Oolites near Further to the west, again, the false-bedded limestones are stillmore largely exposed in a quarry with a 14-feet face, now in work,where they are extremely uniform and smooth, in beds from 1 footto 2 feet in thickness, without apparent dip in any direction. Theyare beautiful building-stones, having a fine grain, and being free fromfossils, except a single bed near the top, which contains Trigoniaclavellata, Chemitzia Jieddingtonensis, Nerincea fasciata, Pleuromyatellina, and Echinobrissus scutatus. As no false-bedding is here THE COKALLIAN EOCKS OF ENGLAND. 281 seen, their identity might be considered doubtful; but their aspectand the stratigraphical connexion with the last-described quarriesleave no doubt on the subject, especially as they are overlain closeby by similar flaggy oolites, which contain Trigonia Meriani. In spite, therefore, of their very local nature and their compara-tive paucity of fauna, these false-bedded
